Hugo Black,
Bisso v. Inland Waterways Corporation…
“ As a rule no employer, no person can tell them how to perform their pilotage duties. When the law does not prescribe their duties, pilots are usually free to act on their own best judgment while engaged in piloting a vessel. Because of these differences between pilots and towage employees generally, contracts stipulating against a pilot's negligence cannot be likened to contracts stipulating against towers' negligence. It is one thing to permit a company to exempt itself from liability for the negligence of a licensed pilot navigating another company's vessel on that vessel's own power. ”
